The flame temperature increases significantly when the air hole is closed in a Bunsen burner because the flame becomes fuel-rich, leading to incomplete combustion. This can result in a sooty, yellow flame with a lower efficiency and higher temperature, reaching up to 1300°C (2372°F) due to the excess fuel. However, this can also create safety hazards, such as the potential for carbon monoxide production.

The blue flame of the Bunsen burner is when it is hottest. The yellow flame is the safety flame. you should always start the burner on the safety flame which is produced when the holes on its base are closed.
The hole on a Bunsen burner should be closed to create a safety flame. This flame is smaller and more controlled, reducing the risk of accidents.
The chimney on a Bunsen burner helps to regulate the amount of air entering the burner, which in turn controls the intensity of the flame. By adjusting the chimney, you can change the appearance and temperature of the flame produced by the Bunsen burner.
The stopcock on a Bunsen burner is used to control the airflow into the burner. By adjusting the stopcock, you can regulate the amount of oxygen that reaches the flame, which allows you to control the flame size and temperature.
The name is a "safety flame". This is when the air hole on the Bunsen burner is closed, resulting in a flame with a yellow, sooty appearance. It is used for low-temperature heating applications.
When the air hole of a Bunsen burner is closed, the flame temperature can reach up to around 1,400°C (2,550°F). This is because the closed air hole restricts air from entering the burner, leading to incomplete combustion and a hotter, more sooty flame.

The maximum temperature that can be achieved by the yellow flame of a Bunsen burner is around 1,000 to 1,300 degrees Celsius. The temperature can vary depending on the air-to-gas ratio and the quality of the burner.
The blue flame of the Bunsen burner is when it is hottest. The yellow flame is the safety flame. you should always start the burner on the safety flame which is produced when the holes on its base are closed.
The blue flame of a Bunsen burner has a temperature between 500 0C and 700 0C.
The hole on a Bunsen burner should be closed to create a safety flame. This flame is smaller and more controlled, reducing the risk of accidents.
Yes, the flame of a Bunsen burner with a closed air hole can still be used for heating, but it will produce a cooler, more yellow flame compared to a Bunsen burner with an open air hole. Adjusting the air hole allows for control of the flame temperature.
The chimney on a Bunsen burner helps to regulate the amount of air entering the burner, which in turn controls the intensity of the flame. By adjusting the chimney, you can change the appearance and temperature of the flame produced by the Bunsen burner.
The "air-hole" of a bunsen burner allows some of the flame to escape so that the heating flame does not become too hot. A flame that is too hot can damage laboratory equipment. When the air hole is closed it is a yellow sooty flame like the fires we have at home.
No. The lowest temperature , with oxygen closed off and a yellow flame , is about 1000 degrees Celsius. With oxgen feed open temperature of the flame can reach 1300 degrees.
The temperature of a Bunsen burner is regulated by gas and airflow. The gas is controlled by a flow valve and the air is controlled by a screw mechanism on the collar. Different type of nozzles can control the flame's shape. The Bunsen burner was invented in 1855 by Robert Wilhelm Bunsen (1811-1899).
